TECHNICAL FIELD

The present invention relates to the field of interaction device applications, and in particular, to a method, an interaction device, a server, and a system for speech recognition.

BACKGROUND

In the prior art, a user can flexibly and independently download various applications (application) for an interaction device (User Equipment, UE for short). However, not all these applications are provided by terminal manufacturers. An application that does not come with an interaction device but is acquired by a user is referred to as a third-party application, for example, applications in the App store (APP store) of Apple and the Android market (android market). A third-party application may also be a program that is not authorized to start by means of speech before delivery of a device. A third-party application is a program set or an instruction set that is independent of an operating system but can be invoked and executed in an operating environment of an operating system. With a large number of third-party applications, applications available for users to select are enriched significantly. Currently, two most common operating systems of interaction devices are the Android (Android) operating system and the Apple operating system (iOS for short), both of which can support third-party applications. On the Android platform, a third party can upload a developed application to the Android market for sale; on the iOS platform, a third party can upload a developed application to the App store for sale.

A user of an interaction device can download applications in the Android market or the App store to the interaction device by connecting to a network, where these applications may be free of charge or chargeable, and these applications include the most common software, for example, map, social messaging software QQ, instant messaging software Skype, or shopping software Taobao. The foregoing applications are presented on a terminal as icons. When the user needs to start a third-party application, the user taps a corresponding icon on the touchscreen to trigger starting of the third-party application.

For the interaction device, how to start a third-party application more intelligently by means of speech recognition without tapping a corresponding icon but is a difficult problem.

DESCRIPTION OF EMBODIMENTS

The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are a part rather than all of the embodiments of the present invention.

The term “and/or” in this specification describes only an association relationship for describing associated objects and represents that three relationships may exist. For example, A and/or B may represent the following three cases: Only A exists, both A and B exist, and only B exists. In addition, the character “/” in this specification generally indicates an “or” relationship between the associated objects.

Speech recognition technologies are technologies that enable a machine, that is, an apparatus, to convert a speech signal into a corresponding text or command by using recognition and understanding processes. The speech recognition technologies mainly include three aspects: feature extraction technologies, pattern matching criteria, and model training technologies.

In the prior art, the speech recognition technologies generally output a recognition result in a form of text or command. In an entire speech recognition process, a speech signal is input and processed, and then text content is output or a command is output to drive another device, which changes a conventional manner of mouse or keyboard input.

In the prior art, an interaction device may include, for example, a smart phone (smart phone), a tablet computer (Tablet PC), and a game console. The foregoing interaction device generally has a speech recognition function, and accuracy of conversion from speech to a text by the speech recognition function is continuously improved. However, when a third-party application is started on the interaction device, the application can be invoked only by means of tapping or mouse clicking. Therefore, a user hopes to improve an intelligence level of the interaction device, for example, the third-party application can be directly started by speech recognition. An embodiment of the present invention provides such a method, which can implement an issue that a third-party application is directly started according to a speech signal of a user.

FIG. 2 is a schematic flowchart of a speech recognition method according to a second embodiment of the present invention. In the second embodiment, an interaction device executes this method, and a user downloads a third-party application to the interaction device. The interaction device includes at least a speech recognizing unit, a parsing unit, a determining unit, a starting unit, a storage unit, and the like.

S21. The interaction device receives a first speech signal.

Here, the first speech signal is words of a user, for example, “Is old Hu online”. The interaction device may receive the first speech signal by using a microphone.

S22. The interaction device converts the first speech signal to obtain one or more first texts.

After receiving the first signal, a speech recognizing unit of the interaction device converts speech waveforms into a text (Speech to text), where the text is corresponding to the foregoing first text. A first text output by the speech recognizing unit after conversion may be “Is old Hu online”, “Is old Hu first”, and/or “Is Tiger online” and is sent to a determining unit for processing. In this embodiment of the present invention, the interaction device includes the speech recognizing unit, the parsing unit, the determining unit, and the starting unit, which separately execute a specific step in the second embodiment of the present invention. In another embodiment, the speech recognizing unit and the parsing unit, the determining unit, and the starting unit may be included in different devices.

S23. The interaction device separately scores semantics (semantic) of at least two first texts according to a predetermined scoring rule and according to naturalness and coherence of the semantics of the at least two first texts.

The parsing unit of the interaction device lists corresponding optional semantics according to the first text, for example, “old Hu” exists in an address book of the interaction device, and a word, such as “online”, whose occurrence probability is high, exists in previous speech input of the user. The parsing unit sorts multiple combinations, for example, “Is old Hu online”, “Is old Hu first”, and “Is Tiger online”, and scores each combination according to naturalness and coherence of the semantics, where a higher score represents better naturalness and coherence of the semantics.

Optionally, in a different embodiment, the parsing unit may set a scoring threshold, and score various combinations of the semantics of the first text according to the predetermined scoring rule. The parsing unit performs a task analysis and accesses a storage unit only when a score of semantics of the first text is the highest and exceeds a predetermined threshold.

S28. When the interaction device converts the first speech signal and obtains only one first text, it directly determines first target semantics by using the semantics of the first text. The scoring processes S23 and S24 can be skipped; instead, the step S25 and subsequent steps are executed.

S24. The interaction device acquires, from the semantics of the at least two first texts, semantics with a highest score and of a first text as first target semantics.

Optionally, in an embodiment, if the parsing unit of the interaction device acquires only one piece of semantics with the highest score, for example, “Old Hu is online”, of a first text, S25 is executed next.

In another embodiment, when no first text has a semantics score exceeding the predetermined threshold, or when two or more first texts have a semantics score exceeding the predetermined threshold, the parsing unit may feed back, to the speech recognizing unit according to a context, a command indicating that more information needs to be input. Optionally, the parsing unit analyzes, according to a context of the semantics, that “online” is closely related to text communication and speech communication, that is, feeds back a command to the speech recognizing unit, for example, “Do you hope to have online speech communication or online text communication”. The speech recognizing unit may feed back the command to the user by means of speech or text, so that the user inputs more requirements. For example, the user answers “speech”, and therefore a “speech” requirement is added; and the parsing unit uses “speech” and “online” as the first target semantics.

S25. The interaction device determines, according to the first target semantics, a third-party application object corresponding to the first target semantics.

The determining unit of the interaction device determines a related task according to the selected first target semantics, for example, a task corresponding to “online” is a social task; and the starting unit needs to start a corresponding third-party application, such as QQ and/or Skype. For ease of description, in this specification, a candidate third-party application is referred to as a third-party application object. The determining unit may select at its own, based on an association relationship between predefined semantics and a third-party application or according to use frequency of a third-party application, to determine a third-party application object by using the first target semantics, which is not limited in the present invention.

In an embodiment, only one third-party application object corresponding to the first target semantics is determined according to the first target semantics, for example, instant messaging software Skype.

In another embodiment, the interaction device may further include a sending unit and a receiving unit. If the number of determined third-party application objects is greater than or equal to two, the interaction device acquires information about all third-party application objects that are associated with the first target semantics; the sending unit sends prompt information, where the prompt information includes the information about the third-party application objects and is used to prompt the user to further send, according to the information about the third-party application objects, a selection instruction, so that the determining unit selects a target third-party application object from all the third-party application objects that are associated with the first target semantics; and the receiving unit receives the selection instruction, and the determining unit selects a corresponding target third-party application object specifically according to the received selection instruction; correspondingly, the starting unit acquires a third-party application that is associated with the target third-party application object and starts the third-party application.

If at least two third-party application objects are found according to the first target semantics, for example, the instant messaging software Skype and social messaging software QQ, the determining unit may feed back, to the speech recognizing unit according to a context, a command indicating that more information needs to be input, for example, feed back a command to the speech recognizing unit, for example, “Do you hope to have instant communication by Skype or social communication by QQ”. The speech recognizing unit may feed back the command to the user by means of speech or text, so that the user inputs more requirements. If the user answers “Skype”, and therefore the parsing unit uses “Skype” as second target semantics. Next, the determining unit determines, according to the second target semantics, that a target third-party application object is the instant messaging software Skype.

S26. The interaction device acquires, from a third-party application registry, a third-party application that is associated with the determined third-party application object and starts the third-party application.

The starting unit of the interaction device searches a third-party application registration information table for the determined third-party application and starts the third-party application.

After determining a specific third-party application, the starting unit accesses the storage unit. The storage unit stores a third-party application registration information table that is generated when the interaction device is powered on or a third-party application registration information table that is generated when a program is installed. The starting unit finds a corresponding program, for example, Skype, and starts the program. Different from a default application registry that is provided with the interaction device before delivery, the third-party application registration information table may be generated when a third-party application is installed, and may also be generated when the interaction device is powered on after the third-party application is installed, as long as the third-party application registration information table is generated before a third-party application that is associated with the determined third-party application object is acquired from the third-party application registry and the third-party application is started. In this embodiment, the third-party application registration information table is stored in the interaction device. In another embodiment, the third-party application registration information table may also be stored in another device except the interaction device, or be stored in both the interaction device and another device.

S27. After starting the third-party application, the interaction device sends a semantics command of the first target semantics to the third-party application, so that the third-party application invokes, according to the semantics command of the first target semantics, an API (Application Programming Interface, application programming interface) that matches the started third-party application, and acquires a required hardware and/or software resource by using the API.

FIG. 3 is a schematic diagram of invoking, after a third-party application is started, an interaction device according to an embodiment of the present invention. After starting a third-party application 32, an interaction device 31 communicates with the third-party application 32 by using a defined API 33. If a third-party application needs to enable video and voice chat functions, it invokes a camera (camera) 35 and a microphone (microphone) 36 of the interaction device by using a video API and an audio API interface that are predefined in an operating system 34 of the interaction device. In an existing operating system of an interaction device, thousands of APIs are defined to support various third-party applications, so as to implement different functions. By using these APIs, third-party applications are capable of communicating with a platform of the interaction device and invoking various resources of the interaction device.

For example, after a third-party application is started, the third-party application receives a semantics command of a parsing unit, and completes a corresponding operation according to the semantics command For example, after the third-party application QQ is started, the parsing unit sends a semantics command to QQ, where the command may also be transferred by a predefined API; after receiving the command, QQ searches a buddy list of QQ for a status of a communication object, that is, a friend whose name is “Old Hu”, and feeds back the status information to the parsing unit; and the parsing unit translates the status information into corresponding semantics, and outputs the semantics to the user by using a speech recognizing unit, for example, finally outputs, for example, “Old Hu is not online” in a form of speech information to notify the user. In this process, the third-party application may require user authentication, and a user account and a password are required to be input, where this type of information is fed back by the third-party application to the user by using the parsing unit and the speech recognizing unit; and the user inputs a corresponding account and password by means of speech or keyboard.

In the second embodiment of the present invention, the user only needs to send a command by speech, and the interaction device can recognize the speech, further perform semantic analysis, and finally start a third-party application; in addition, the interaction device may further feed back status information related to the third-party application to the user after starting the third-party application. This provides a new method for starting a third-party application and significantly facilitates use of the user.

Text information interacted between the foregoing units such as the speech recognizing unit and the parsing unit may be decoded code and may be presented to the user in a form of speech or onscreen text.

According to this embodiment of the present invention, with a speech recognition function, a third-party application corresponding to a speech signal of a user can be determined according to the speech signal and by means of semantic analysis; and third-party application registry information is searched for and a third-party program is started, so that the user does not need to tap the third-party application to start the corresponding program, thereby providing more intelligent service for the user and facilitating use for the user.

FIG. 4 is a schematic architecture diagram of a third-party application supporting a speech recognition function according to a third embodiment of the present invention. In the third embodiment, an interaction device has a speech recognition function, and a user downloads a third-party application to the interaction device, where different from a third-party application in the second embodiment, the third-party application itself also supports the speech recognition function and can execute a related operation according to speech input of the user. Therefore, processes of recognizing and starting a corresponding third-party application according to a speech signal of the user in the second embodiment are the same as that in the third embodiment, and for brevity, details are not repeatedly described herein. A difference lies in a process of executing a task by the third-party application after the third-party application is started in the third embodiment.

Referring to FIG. 4, after a third-party application 41 is started, because the third-party application 41 itself has the speech recognition function, it can directly receive a speech signal 42 of the user, recognize the speech signal 42 to obtain a corresponding command, and execute a related operation. The third-party application receives the speech signal 42 of the user, converts the speech signal 42 to obtain a text, completes parsing of semantics of the text, and executes a task corresponding to the semantics. Optionally, the third-party application 41 may implement semantic analysis and task execution by using a third-party server 43 corresponding to the third-party application 41. When according to a semantics command of the text, the third-party application 41 needs to invoke a resource of an interaction device 44, the third-party application 41 contacts the interaction device by using an API 46 defined by an operating system 45 of the interaction device, and starts the related resource, for example, invokes a camera 47 and a microphone 48 to perform video communication. For example, if the third-party application started by the interaction device is QQ, and a corresponding third-party server is, for example, a server of Tencent, communication between the third-party application and the third-party server may be a private interface and a protocol that are defined by a third party. If the third-party application is a map and the third-party application needs to invoke GPS information of the interaction device, address information of the interaction device can be queried by using a corresponding API, and for specific map information, corresponding map information can be acquired by the third-party application by accessing a third-party server of the third-party application.

FIG. 5 is a schematic architecture diagram of a system 50 for speech recognition according to a fourth embodiment of the present invention. The system 50 includes an interaction device 51 and a server 52. The interaction device 51 may include a speech recognizing unit 511, a storage unit 512, an operating system 513, a camera 514, a microphone 515, and the like. The server 52 may include third-party applications 522, a storage unit 523, a parsing unit, a determining unit, and a starting unit, where the parsing unit, the determining unit, and the starting unit are marked as 521 in FIG. 5. The interaction device 51 is connected to the server 52 by using a network 53. The operating system 513 defines multiple APIs 516 that are used to support various third-party applications 522.

In the system for speech recognition in FIG. 5, the interaction device has only a speech recognition function. Functions of semantic analysis and starting of the third-party applications are completed by the server, and the third-party applications are stored in the server. Optionally, these third-party applications do not support the speech recognition function. The storage unit can be included in both the interaction device and the server, or be placed on either of them. When the starting unit accesses the storage unit, the starting unit may alternatively select one storage unit. The interaction device is connected to the server by using the network, where the network provides a pipe for communication between the interaction device and the server, which may be a wireless network or a wired network.

FIG. 6 is a schematic flowchart of a speech recognition method, based on the architecture of the system 50 in FIG. 5, according to a fifth embodiment of the present invention.

S61. An interaction device converts a first speech signal to obtain one or more first texts and sends the first text to a server.

Here, the first speech signals are words of a user, for example, “Is Old Hu online”. After the first speech signal is received by a microphone of the interaction device, speech waveforms are converted into a first text by a speech recognizing unit of the interaction device. For example, a first text output by the speech recognizing unit after conversion may be “Is old Hu online”, “Is old Hu first”, and/or “Is Tiger online” and is sent to the server for processing.

S62. The server parses the one or more first texts to obtain first target semantics. This step may include the following specific content.

In this embodiment, the server includes a parsing unit, a determining unit, and a starting unit. The parsing unit of the server receives at least two first texts that are sent by the interaction device and are obtained through conversion from the first speech signal, scores semantics of each first text of the at least two first texts according to a predetermined scoring rule and according to naturalness and coherence of the semantics of the at least two first texts, where a higher score represents better naturalness and coherence of the semantics, and acquires semantics with a highest and of the first text as the first target semantics.

Optionally, the parsing unit lists corresponding optional semantics according to the first text, for example, “old Hu” exists in an address book of the interaction device, and a word, such as “online”, whose occurrence probability is high, exists in previous speech input of the user. The parsing unit sorts multiple combinations, for example, “Is old Hu online”, “Is old Hu first”, and “Is Tiger online”, and scores each combination according to naturalness and coherence of the semantics, where a higher score represents better naturalness and coherence of the semantics.

Optionally, in a different embodiment, the parsing unit may set a scoring threshold, score various combinations of the semantics of the first text according to the predetermined scoring rule, and in the semantics of the at least two first texts, use semantics, with a highest score, of the first text and exceeds a preset threshold as the first target semantics.

In an embodiment, if there is only one piece of semantics with a highest score, for example, “Old Hu is online”, the parsing unit uses the semantics of the first text as the first target semantics.

In another embodiment, when no first text has a semantics score exceeding the predetermined threshold, or when two or more first texts have a semantics score exceeding the predetermined threshold, the parsing unit may feed back, to the speech recognizing unit of the interaction device according to a context, a command indicating that more information needs to be input. As described in the foregoing embodiment, after the scoring, the semantics “online” does not meet the scoring threshold of the semantics. The parsing unit analyzes, according to a context of the semantics, that “online” is closely related to text communication and speech communication, that is, feeds back a command to the speech recognizing unit, for example, “Do you hope to have online speech communication or online text communication”. The speech recognizing unit may feed back the command to the user by means of speech or text, so that the user inputs more requirements. For example, the user answers “speech”, and therefore a “speech” requirement is added; and the parsing unit uses “speech” and “online” as the first target semantics.

Optionally, in a different embodiment, when the interaction device converts the first speech signal, obtains only one first text, and sends the first text to the server, the server directly determines the first target semantics by using semantics of the first text, and further executes the step S63 and subsequent steps.

S63. The server determines, according to the first target semantics, a third-party application object corresponding to the first target semantics.

The determining unit determines a related task according to the selected first target semantics, for example, a task corresponding to “online” is a social task; and the starting unit needs to start a corresponding third-party application, such as QQ and/or Skype. For ease of description, in this specification, a candidate third-party application is referred to as a third-party application object. The determining unit may select at its own, based on an association relationship between predefined semantics and a third-party application or according to use frequency of a third-party application, to determine a third-party application object by using the first target semantics, which is not limited in the present invention.

In an embodiment, only one third-party application object corresponding to the first target semantics is determined according to the first target semantics, for example, instant messaging software Skype.

In another embodiment, the server may further include a sending unit and a receiving unit. If the number of determined third-party application objects is greater than or equal to two, the server acquires information about all third-party application objects that are associated with the first target semantics; the sending unit sends prompt information, where the prompt information includes the information about the third-party application objects and is used to prompt the user to further send, according to the information about the third-party application objects, a selection instruction, so that the determining unit selects a target third-party application object from all the third-party application objects that are associated with the first target semantics; and the receiving unit receives the selection instruction, and the determining unit selects a corresponding target third-party application object according to the selection instruction; correspondingly, the starting unit acquires a third-party application that is associated with the target third-party application object and starts the third-party application.

If at least two third-party application objects are found according to the first target semantics, for example, the instant messaging software Skype and social messaging software QQ, the processing unit may feed back, to the speech recognizing unit according to a context, a command indicating that more information needs to be input; the processing unit feeds back a command to the speech recognizing unit, for example, “Do you hope to have instant communication by Skype or social communication by QQ”. The speech recognizing unit may feed back the command to the user by means of speech or text, so that the user inputs more requirements. For example, the user answers “Skype”, and therefore the parsing unit uses “Skype” as second target semantics. Next, the determining unit determines, according to the second target semantics, that a target third-party application object is the instant messaging software Skype.

S64. The server acquires, from a third-party application registry, a third-party application that is associated with the determined third-party application object, starts the third-party application, and sends a response feedback to the interaction device.

The starting unit of the server may alternatively accesses a storage unit of the server or a storage unit of the interaction device, find a determined third-party application according to a third-party application registration information table, and start the third-party application.

After determining a specific third-party application, the starting unit accesses the storage unit. The storage unit of the interaction device stores a third-party application registration information table, and the storage unit of the server stores a third-party application and a third-party application registration information table. Different from a default application registry that is provided with the interaction device before delivery, a third-party application registration information table may be generated when a third-party application is installed, and may also be generated when the interaction device is powered on after the third-party application is installed. In this embodiment, when the third-party application registration information table is stored in the storage unit of the interaction device, the starting unit of the server needs to access the storage unit of the interaction device to acquire a third-party application and start the third-party application.

S65. The interaction device receives the response feedback sent by the server.

After the starting unit of the server starts the third-party application, the sending unit sends a semantics command of the first target semantics to the third-party application, so that the third-party application invokes, according to the semantics command of the first target semantics, an API (Application Programming Interface, application programming interface) that matches the started third-party application, and acquires a required hardware and/or software resource by using the API.

Optionally, after the third-party application is started, the third-party application receives a semantics command of the parsing unit, and completes a corresponding operation according to the semantics command For example, after the third-party application QQ is started, the parsing unit sends a semantics command to QQ, where the command may also be transferred by a predefined API; after receiving the command, QQ searches a buddy list of QQ for a status of a communication object, that is, a friend whose name is “Old Hu”, and feeds back the status information to the parsing unit; and the parsing unit translates the status information into corresponding semantics, and outputs the semantics to the user by using the speech recognizing unit of the interaction device, for example, finally outputs, for example, “Old Hu is not online” in a form of speech information to notify the user. In this process, the third-party application may require a user authentication, and a user account and a password are required to be input, where this kind of information is fed back by the third-party application to the user by using the sending unit of the server and the speech recognizing unit of the interaction device; and the user inputs a corresponding account and password by means of speech or keyboard.

Text information interacted between the foregoing units such as the speech recognizing unit and the parsing unit may be decoded code and may be presented to the user in a form of speech or onscreen text.

According to this embodiment of the present invention, with a speech recognition function, a third-party application corresponding to a speech signal of a user can be determined according to the speech signal and by means of semantic analysis; and third-party application registry information is searched for and a third-party program is started, so that the user does not need to tap the third-party application to start the corresponding program, thereby providing more intelligent service for the user and facilitating use for the user.

Optionally, in another sixth embodiment, a difference between this embodiment and the fourth and fifth embodiments lies in that a third-party application itself also supports a speech recognition function and can execute a related operation according to speech input of a user. Therefore, processes of recognizing and starting a corresponding third-party application according to a speech signal of the user in the sixth embodiment are the same as that in the fourth embodiment, refer to the fifth embodiment, and for brevity, details are not repeatedly described herein. A difference lies in a process of executing a task by the third-party application after the third-party application is started in the sixth embodiment.

After the third-party application is started, because the third-party application itself has the speech recognition function, it can directly receive a speech signal of the user, and execute a related operation according to the command The third-party application receives the speech signal of the user, converts the speech signal to obtain a text, completes parsing of semantics of the text, and executes a task corresponding to the semantics. The third-party application implements semantic analysis and task execution by using a third-party server corresponding to the third-party application. When according to a semantics command of the text, the third-party application needs to invoke a resource of an interaction device, the third-party application contacts the interaction device by using an API defined by an operating system of the interaction device, and starts the related resource, for example, invokes a camera and a microphone to perform video communication. In this case, if the third-party application started by the interaction device is QQ, and a corresponding third-party server is, for example, a server of Tencent, communication between the third-party application and the third-party server may be a private interface and a protocol that are defined by a third party itself. If the third-party application is a map and the third-party application needs to invoke GPS information of the interaction device, address information of the interaction device can be queried by using a corresponding API, and for specific map information, corresponding map information can be acquired by the third-party application by accessing a third-party server of the third-party application.

The interaction device 70 may include a parsing unit 71, a determining unit 72, a starting unit 73, a storage unit 74, and the like. For example, the interaction device may be an apparatus such as a mobile terminal or a tablet computer (Tablet PC).

The parsing unit 71 parses one or more first texts to obtain first target semantics, where the first text is obtained through conversion from a first speech signal.

The determining unit 72 determines, according to the first target semantics acquired by the parsing unit, a third-party application object corresponding to the first target semantics, where a third-party application that is associated with the third-party application object is a program that is not authorized to start by means of speech before delivery of a device.

The starting unit 73 accesses the storage unit, acquires, from a third-party application registry stored by the storage unit, a third-party application that is associated with the determined third-party application object, and starts the third-party application.

The storage unit 74 stores the third-party application registry and the third-party application.

The interaction device 70 can execute the speech recognition method in the first embodiment of the present invention. The details are not repeatedly described herein.

The parsing unit 82, the determining unit 83, the starting unit 84, and the storage unit 85 of the interaction device 80 are the same as or similar to the parsing unit 71, the determining unit 72, the starting unit 73, and the storage unit 74 of the interaction device 70. A difference lies in that the interaction device 80 further includes the speech recognizing unit 81, the generating unit 86, the sending unit 87, and the receiving unit 88.

The speech recognizing unit 82 converts a first speech signal to obtain one or more first texts and sends the one or more first texts to the parsing unit 82.

Before the interaction device acquires, from a third-party application registry, a third-party application that is associated with a determined third-party application object and starts the third-party application, the generating unit 86 generates the third-party application registry and sends the third-party application registry to the storage unit 85.

The parsing unit 82 specifically converts the first speech signal to obtain at least two first texts, scores semantics of each first text of the at least two first texts according to a predetermined scoring rule and according to naturalness and coherence of the semantics of the at least two first texts, where a higher score represents better naturalness and coherence of the semantics, and acquires, from the semantics of the at least two first texts, semantics with a highest score and of the first text as the first target semantics.

The parsing unit 82 specifically acquires, from the semantics of the at least two first texts, semantics, with a highest score, of the first text and exceeds a preset threshold as the first target semantics.

The determining unit 83 specifically determines, according to the first target semantics, all third-party application objects corresponding to the first target semantics, and if the number of the third-party application objects is greater than or equal to two, acquires information about all the third-party application objects that are associated with the first target semantics; the sending unit 87 sends prompt information, where the prompt information includes the information about the third-party application objects and is used to prompt a user to further send, according to the information about the third-party application objects, a selection instruction, so that the determining unit 83 selects a target third-party application object from all the third-party application objects that are associated with the first target semantics; the receiving unit 88 receives the selection instruction, and the determining unit 83 specifically selects a corresponding target third-party application object according to the received selection instruction; and the starting unit specifically acquires, from the third-party application registry stored by the storage unit, a third-party application that is associated with the target third-party application object and starts the third-party application.

The speech recognizing unit 81 further converts, when the selection instruction is a second speech signal, the second speech signal to obtain a second text and sends the second text to the parsing unit 82; the parsing unit 82 further parses the second text to acquire second target semantics; and the determining unit 83 determines a corresponding target third-party application object according to the second target semantics.

After starting the third-party application, the starting unit 84 further sends a semantics command of the first target semantics to the third-party application, so that the third-party application invokes, according to the semantics command of the first target semantics, a third-party application interface API that matches the started third-party application.

The interaction device 80 implements the speech recognition method in the first, second, or third embodiment of the present invention. For brevity, details are not repeatedly described herein.

According to this embodiment of the present invention, with a speech recognition function, a third-party application corresponding to a speech signal of a user can be determined according to the speech signal and by means of semantic analysis; and third-party application registry information is searched for and a third-party program is started, so that the user does not need to tap the third-party application to start the corresponding program, thereby providing more intelligent service for the user and facilitating use for the user.

FIG. 9 is a schematic block diagram of a server 90 for speech recognition according to a ninth embodiment of the present invention. The server 90 includes a parsing unit 91, a determining unit 92, a starting unit 93, a storage unit 94, and the like. The server 90 provides support service for an interaction device.

The parsing unit 91 parses one or more first texts to obtain first target semantics, where the first text is obtained through conversion from a first speech signal.

The determining unit 92 determines, according to the first target semantics acquired by the parsing unit, a third-party application object corresponding to the first target semantics, where a third-party application that is associated with the third-party application object is a program that is not authorized to start by means of speech before delivery of a device.

The starting unit 93 acquires, from a third-party application registry stored by the storage unit 92, a third-party application that is associated with the determined third-party application object and starts the third-party application.

The storage unit 92 stores the third-party application registry and the third-party application.

FIG. 10 is a schematic block diagram of a server 100 for speech recognition according to a tenth embodiment of the present invention. The server 100 includes a parsing unit 101, a determining unit 102, a starting unit 103, a storage unit 104 and a generating unit 105, a sending unit 106 and a receiving unit 107, and the like. The parsing unit 101, the determining unit 102, the starting unit 103, and the storage unit 104 of the server 100 are the same as or similar to the parsing unit 91, the determining unit 92, the starting unit 93, and the storage unit 94 of the server 90. A difference lies in that the server 100 further includes the generating unit 105, the sending unit 106, and the receiving unit 107.

Before the server acquires, from a third-party application registry, a third-party application that is associated with a determined third-party application object and starts the third-party application, the generating unit 105 generates the third-party application registry and sends the third-party application registry to the storage unit 104.

The parsing unit 101 specifically scores, according to a predetermined scoring rule and according to naturalness and coherence of semantics of at least two first texts that are obtained through conversion from a first speech signal, semantics of each first text of the at least two first texts, where a higher score represents better naturalness and coherence of the semantics, and acquires, from the at least two first texts, semantics with a highest score and of the first text as the first target semantics.

FIG. 11 is a schematic block diagram of an apparatus 110 for speech recognition according to an eleventh embodiment of the present invention. The apparatus 110 includes a processor 111, a memory 112, and the like.

The memory 112 may include a RAM and a ROM, or any fixed storage medium or portable storage medium, which is configured to store a program that can execute embodiments of the present invention, data to be processed in the embodiments of the present invention, a third-party application, or the like.

The processor 111 is configured to execute a program, which is stored by the memory 112, of the embodiments of the present invention and perform bidirectional communication with another apparatus by using, for example, a bus.

In an implementation manner of the apparatus 110, the processor 111 parses one or more first texts to obtain first target semantics, where the first text is obtained through conversion from a first speech signal; determines, according to the acquired first target semantics, a third-party application object corresponding to the first target semantics, where a third-party application that is associated with the third-party application object is a program that is not authorized to start by means of speech before delivery of a device; and accesses the memory, acquires, from a third-party application registry stored by the memory, a third-party application that is associated with the determined third-party application object, and starts the third-party application. The memory 112 stores the third-party application registry and the third-party application, and the processor 111 executes an instruction of the foregoing method.

When the apparatus 110 may further include a device or a module that collects speech signals, for example, a microphone, the processor 111 converts a first speech signal collected by the microphone or the like to obtain one or more first texts.

In addition, the processor 111 specifically converts the first speech signal to obtain at least two first texts, scores semantics of each first text of the at least two first texts according to a predetermined scoring rule and according to naturalness and coherence of the semantics of the at least two first texts, where a higher score represents better naturalness and coherence of the semantics, and acquires, from the semantics of the at least two first texts, semantics with a highest score and of the first text as the first target semantics.

The processor 111 further determines, according to the first target semantics, all third-party application objects corresponding to the first target semantics; and if the number of the third-party application objects is greater than or equal to two, acquires information about all the third-party application objects that are associated with the first target semantics; sends prompt information, where the prompt information includes the information about the third-party application objects and is used to prompt a user to further send, according to the information about the third-party application objects, a selection instruction, so as to select a target third-party application object from all the third-party application objects that are associated with the first target semantics; receives the selection instruction, selects a corresponding target third-party application object according to the received selection instruction; and acquires, from the third-party application registry stored by the memory 112, a third-party application that is associated with the target third-party application object and starts the third-party application.

The processor 111 further converts, when the selection instruction is a second speech signal, the second speech signal to obtain a second text, parses the second text to acquire second target semantics, and determines a corresponding target third-party application object according to the second target semantics.

Before acquiring, from the third-party application registry, the third-party application that is associated with the determined third-party application object and starting the third-party application, the processor 111 generates the third-party application registry.

After starting the third-party application, the processor 111 further sends a semantics command of the first target semantics to the third-party application, so that the third-party application invokes, according to the semantics command of the first target semantics, a third-party application interface API that matches the started third-party application.

Before the apparatus 110 acquires, from the third-party application registry, the third-party application that is associated with the determined third-party application object and starts the third-party application, the processor 111 generates the third-party application registry and sends the third-party application registry to the memory 112.

In another implementation manner, when the apparatus 110 does not include a device or a module that collects speech signals, for example, a microphone, the processor 111 further receives, before parsing a first text to obtain first target semantics, the first text sent by another apparatus; parses the first text to obtain the first target semantics, where optionally, the first text is obtained through conversion from a first speech signal and at least two first texts are obtained; determines, according to the acquired first target semantics, a third-party application object corresponding to the first target semantics; and acquires, from a third-party application registry stored by the memory 112, a third-party application that is associated with the determined third-party application object and starts the third-party application. The memory 112 stores the third-party application registry and the third-party application, and the processor 111 executes an instruction of the foregoing method.

The processor 111 generates, when a third-party application is installed on the apparatus 1100 or after the apparatus 110 is powered on, the third-party application registry and sends the third-party application registry to the memory 112.

The processor 111 specifically scores, according to a predetermined scoring rule and according to naturalness and coherence of the semantics of at least two first texts that are obtained through conversion from the first speech signal, semantics of each first text of the at least two first texts, where a higher score represents better naturalness and coherence of the semantics; and acquires, from the semantics of the at least two first texts, semantics with a highest score and of the first text whose score as the first target semantics.

The processor 111 specifically acquires, from the semantics of the at least two first texts, semantics, with a highest score, of the first text and exceeds a preset threshold as the first target semantics.

The processor 111 further determines, according to the first target semantics, all third-party application objects corresponding to the first target semantics; and if the number of the third-party application objects is greater than or equal to two, acquires information about all the third-party application objects that are associated with the first target semantics; sends prompt information, where the prompt information includes the information about the third-party application objects and is used to prompt a user to further send, according to the information about the third-party application objects, a selection instruction, so as to select a target third-party application object from all the third-party application objects that are associated with the first target semantics; receives the selection instruction, selects the corresponding target third-party application object according to the received selection instruction; and acquires, from the third-party application registry stored by the memory 112, a third-party application that is associated with the target third-party application object and starts the third-party application.

The processor 111 further parses, when the selection instruction is a second speech signal, the second text to acquire second target semantics, where the second text is obtained through conversion from the second speech signals; and determines a corresponding target third-party application object according to the second target semantics.

After starting the third-party application, the processor 111 further sends a semantics command of the first target semantics to the third-party application, so that the third-party application invokes, according to the semantics command of the first target semantics, a third-party application interface API that matches the started third-party application.

After the processor 111 starts the third-party application, so that the third-party application converts the third speech signal to obtain a third text, and invokes, according to a semantics command of the third text, a third-party application interface API that matches the started third-party application, so that the started third-party application acquires a required hardware or software resource by using the API.
